Oral tuberculosis: a case report and review of the literature

Oral tuberculosis (TB) is a chronic infectious granulomatous disease that can present with ulceration in the oral cavity. This article presents a case of reactivated TB which presented as a painful oral ulcer in a patient on immunosuppressive medication. It is important for clinicians to be aware of TB when considering a differential diagnosis for oral ulceration, especially in patients who have been prescribed biological agents or other immunosuppressive medications. A delay in the diagnosis can have serious consequences to both the individual and the wider community.
